Item_number: 99-ST400I-CMP Categories: , ,

The Pneumatic ST400 stapler was built to solve the problem of using a hammer to drive staples into wooden posts.

We used our engineering expertise to bring this product to market after recognizing a need for it after discussions with our customers. It is compatible with 4mm diameter / 9 Gauge (40mm, 45mm or 50mm / 1 1/2″, 1 3/4″ and 2″ long) staples. The pneumatic ST400 fencing stapler’s aluminum alloy housing means that it is lightweight and corrosion resistant for extreme durability.

This tool is also compatible with the Power Staple Insulator Guide Attachment allowing you to easily erect an electric fence using the PEL/Speedrite/Stafix Wood Post Claw Insulator.
